Example

See Figure 1, Figure 2, and Figure 3, a metering device for solid creams and fats. The whole metering device is similar to a common pen in appearance, and includes the following parts:

(1) A pair of upper and lower cylinders (lower cylinder and upper cylinder) with the same thickness. The lower part of the lower cylinder 1 is an inverted cone with a round hole at the bottom of the inverted cone. The upper end of the lower cylinder 1 has threads in the wall, which can be connected with the upper cylinder 2. There is a partition in the middle of the upper cylinder 2, which divides the upper cylinder 2 into two cavities (the upper cavity of the upper cylinder and the lower cavity of the upper cylinder), and there is a small round hole in the center of the partition Make the two cavities communicate; there are threads on the outer wall of the lower cavity of the upper cylinder, which can be connected with the lower cylinder 1; a certain number of small grooves are opened on the wall of the upper end of the upper cavity of the upper cylinder, and each small groove is located outside the cylinder Surfaces on the same generatrix with equal spacing.

(2) The upper cylinder contains a pair of extruding rods (upper extruding rod and lower extruding rod). The lower end of the lower extruding rod 3 is a thin rubber plug, and the outer circle of the thin rubber plug is in a tight interference fit with the inner wall of the lower cavity of the upper cylinder; the upper end of the lower extruding rod has threads, which can be connected with the upper extruding rod 5; The compression rod 3 passes through the small round hole in the center of the partition, the lower end of the lower extrusion rod 3 (including the thin rubber plug) is in the lower cavity of the upper cylinder, and the upper end is in the upper cavity of the upper cylinder. The upper extruding rod 5 is in the upper cavity of the upper cylinder, and the lower end of the upper extruding rod 5 is connected with the lower extruding rod 3 through the screw thread of the inner wall. There is a cylindrical protrusion in the middle of the upper extruding rod 5 .

(3) A spring 4 is sheathed outside the upper and lower extruding rods, the lower end of the spring is in contact with the partition in the upper cylinder 2, and the upper end of the spring is in contact with the cylindrical protrusion in the middle of the upper extruding rod. The spring is used to support the extrusion rod and the control rod. When subjected to the extrusion force, the elastic deformation shortens, and the kinetic energy is converted into deformation energy. The extrusion rod and the control rod move down to a certain stroke. After unloading, the spring stretches, the deformation disappears and returns to its original shape, the deformation energy is converted into kinetic energy, and the extrusion rod and the control rod are driven to reset.

(4) There is a control rod 6 above the upper extrusion rod. There is a round hole at the lower end of the control rod 6, which can be connected with the upper extrusion rod; there is an elastic hook 10 on the side of the control rod, which can be stuck in the small groove on the upper end of the upper cylinder 2, and click on the small groove. The hook head can also release the elastic hook; the upper end of the control rod is a pressing handle 11.

(5) There is also a cap 7 above the upper cylinder, which has an outer elastic hook on the cap 7, so that the meter can be hung on the pocket of the clothes and is easy to carry.

Principle of the present invention is as follows:

The principle of the present invention is that, according to the cylinder volume calculation formula

V=π.r ² .h (1)

in:

r is the inner radius of the cylinder;

h is the distance between the small grooves on the outer wall of the cylinder, that is, the extrusion stroke.

If a suitable r is specified, and the stroke h of each extrusion is the same, the volume (weight) of the extruded grease is also the same.

When a certain type of precision motor is produced, each motor needs to add grease m=45g, the density of grease ρ=0.9g/cm ³ , assuming that the r of the meter is 4cm, the extrusion stroke $h=\frac{V}{\mathrm{\π}\·r^2}=\frac{m/\mathrm{\ρ}}{\mathrm{\π}\·r^2}=\frac{45/0.9}{\mathrm{\π}\&Center\; Dot;4^2}=0.995\mathrm{cm},$ During the design, the spacing of the small grooves is set at 0.995cm, and a total of 6 small grooves are designed.

Adopt quantifier of the present invention to carry out the method that this lubricating grease is quantified as follows:

(1) Put the lubricating grease to be used in a glass;

(2) Lock the elastic hook of the control rod 6 into the small groove at the uppermost end of the upper cylinder wall. Unscrew the upper and lower cylinders of the quantifier, take down the inverted cone at the lower end of cylinder 1 and the upper end of upper cylinder 2, insert the upper end of the lower cylinder and the lower end of the upper cylinder into the glass, so that the upper and lower cylinders The cavity in the cavity is filled with grease, and inserted several times until the gap in the cavity is completely filled.

(3) Screw the upper and lower cylinders of the doser relative to each other, and use a rag to wipe off the excess grease at the round hole of the inverted cone at the lower end of the lower cylinder.

(4) Press the pressing handle on the upper end of the control rod 6. Make the elastic snap hook of control rod be stuck in the second small groove of upper cylinder wall upper end. The lubricating grease extruded from the round hole of the inverted cone at the lower end of the lower cylinder is the required quantitative lubricating grease.

(5) Then press the pressing handle on the upper end of the control rod again. Make the elastic snap hook of control rod be stuck in the third small groove at the upper end of the cylinder wall. The lubricating grease extruded from the round hole of the inverted cone at the lower end of the lower cylinder is the required quantitative lubricating grease.

(6) Repeat in sequence, so that the elastic hook of the control rod is stuck in the fourth, fifth, and sixth small grooves at the upper end of the upper cylinder wall.

(7) Repeat steps (2)-(6), and repeat in turn. In this way, through cyclic extrusion, quantitative lubricating grease can be obtained many times and quickly.
